Description

TECHNICAL AREA

The present invention belongs to the field of building doors, and relates to the joinery frames of doors with a pivoting leaf with respect to a fixed fixed frame. The invention relates more particularly to a high hinge system for a building door, allowing movement of the leaf relative to the fixed frame.

The invention can also be applied to windows, shutters, gates and the like.

STATE OF THE ART

Conventional frames known in the art to date are generally equipped with pivoting devices for the movable sash relative to the fixed frame, such as hinges, hinges or hinges, mounted between the frame and the sash to allow it to be opened or closed. There are also known systems with a vertical pivot, carried by the threshold or a crosspiece of the frame, cooperating with a keeper or the like fixed to the opening, or even hinges with multiple arms, unfolding during the relative movements of the screw opening. -à-vis the frame.

The solution on a vertical pivot, for example, consists in not using hinges but simply a high joint and a low joint which make it possible to pivot the opening around the common axis of these two joints.

However, all these solutions have drawbacks, among which we can highlight their significant size and especially the need to machine the frame of the opening to fix the hinges or the hinges of the articulation, the presence of these accessories, which are attached and fixed externally on both the frame and the sash, preventing a 180° opening of the latter, for example.

For example, the document DE 19919136 A1 discloses a hinge for a door comprising a male part provided with an axis and a female part receiving said axis, the male and female parts being respectively fixed to lower crosspieces of the opening and of the frame. The document US 3478383A discloses an upper joint between a door and a door frame, said joint comprises a first pivot element and a second pivot element between which engages a pivot pin. The pivot elements have the same structure and provide an identical function, each of said elements receives the pivot axis in the same way.

Furthermore, the aesthetics of the frame, due to the apparent character of these accessories, is mediocre, and its cost price is high due to the separate production of these accessories and the constraints due to their assembly.

In addition, the vertical pivot solution has an imposing high hinge system, involving the use of large sections for the construction of the doors. In addition, this system is clearly visible on a door and requires significant machining of the aluminum bars constituting the door.

Moreover, this solution has an additional drawback due to a large radius of rotation of the profile due to an axis of rotation of the pivot offset with respect to the axis of an upright of the opening.

The male part is able to be fixed to an upright of the opening, and the female part is able to be fixed to a crosspiece of the fixed frame.

In one embodiment, the female part is adapted to be fixed to the crosspiece of the fixed frame by means of an upper insert entirely housed in an interior volume of said crosspiece, the base being fixed to said upper insert.

The base has a bore, said bore receiving at least a first part of the shaft.

In addition and advantageously, the articulation comprises a robust sliding ring placed in the bore of the base and in which the first part of the axis is engaged.

The male part further comprises a lower insert comprising a bore in which is housed at least a second part of the shaft opposite the first end of said shaft.

Advantageously, a security screw engages in the lower insert and allows the blocking of any translation of said lower insert in a longitudinal direction of the jamb of the opening when said security screw is in abutment on a lower edge of a hole realized in said amount.

Advantageously, the joint comprises a cap making it possible to conceal the axis and the base in which it is mounted, at least partially when said joint is isolated from the frame, and completely when said joint is mounted on the frame. .

The male part is able to be fixed to the upright of the sash by means of a locking insert entirely housed in an interior volume of said upright.

In addition, the joint comprises an inclined screw which engages in a hole in the base and a hole in the upper insert, allowing adjustment of the plumb of the sash by tightening said inclined screw after a adjustment of the position of said base relative to the upper insert, this adjustment being achieved by sliding of the base permitted by screws loosened in oblong holes of said base, said screws connecting said base to the upper insert.

Advantageously, the lower insert is fixed to the locking insert.

The invention also relates to a frame for a door, window or the like, comprising a fixed frame and a movable leaf pivoting around said fixed frame, and comprising a hinge as described.

DETAILED DESCRIPTION OF EMBODIMENTS

The picture 1a shows in perspective view a joint 100 according to a non-limiting embodiment of the invention. The articulation 100 is intended to equip any frame comprising at least one fixed frame 300, represented on the figure 8 , and a mobile opening 200, represented on the figure 7 , Pivoting vis-à-vis the frame, such as the usual frames of doors, windows or the like.

The joint 100, according to the illustrated embodiment, comprises an upper insert 10 allowing the attachment of the joint to the frame, a base 20 which cooperates with the upper insert to form the fixed part of the joint, a plug 30 concealing the base, a brush 40, an axle 50, a lower insert 60 wherein said axis is secured, a locking insert 70, a retaining screw 80 supporting the axis and the lower and locking inserts, various screws allowing assembly of the elements mentioned and an inclined screw 96 allowing adjustment of the plumb of the sash.

The different elements of the joint are carpentry elements and can be made in different shapes and sizes and in different materials provided that the desired functionality of the joint is preserved.

In the rest of the description, the terms "top", "bottom", "front", "rear", "upper", "lower" as well as the terms and expressions which may be associated with them or derived therefrom will be understood, unless specified or otherwise obvious, as having the meaning given to them by an observer of a door frame equipped with the joint 100 shown in picture 1a . Given the system of axes represented on the picture 1a , the front and the top are located respectively along the increasing abscissas X and the increasing sides Z.

The upper insert 10, shown in perspective in the exploded view of the figure 1b and in view from below on the figure 4 , is a section having a slightly trapezoidal U-shaped profile defining an internal recess 11. The upper insert 10 has a straight section 12 at a first end and an inclined section 13 at a second end opposite said first end, the inclined section being then parallel to a cutting plane of a profile of the frame in which said upper insert is fixed. The inclination of the inclined section 13 is for example 45° with respect to a longitudinal axis of the upper insert 10.

This condition is however not mandatory and the upper insert may have a straight section at each of its ends.

The upper insert 10 allows the attachment of the joint 100 to the frame and thereby constitutes an interface between the frame and the rest of the joint. Thus, the upper insert 10 is provided with a direct fixing hole 14 allowing a suitable screw, not shown, to tighten said upper insert directly against an upper crosspiece of the frame, with intermediate fixing holes 15, allowing suitable screws passing through the base 20 to tighten said base against the upper insert and said upper insert against the upper crosspiece of the frame, and an inclined hole 16 for adjusting the plumb of the sash by tightening a suitable screw.

In the following, the profile of an upright of the sash and the profile of a crosspiece of the frame of a frame will be respectively designated by jamb of the sash and crosspiece of the frame, which represent the parts of the frame to which said profiles are secured.

Preferably the inclined hole 16 for adjusting the plumb has an inclination with respect to the longitudinal axis of the upper insert 10 substantially equal to the inclination of the inclined section 13 with respect to said longitudinal axis, for example 45°, thus limiting the effort required to adjust the plumb.

Furthermore, each of the holes 14, 15 and 16 of the upper insert 10 opens out, when the upper insert is positioned at the level of the upper crosspiece of the frame, on a similar hole made in said upper crosspiece.

In the embodiment illustrated in figure 4 , the direct fixing hole 14 is a smooth hole 6 mm in diameter for example. The intermediate fixing holes 15 are tapped holes having an M5 metric thread, that is to say with a pitch of 0.8 mm and a bore diameter of 4.2 mm. In the following, the metric threads being standardized and known to those skilled in the art, the characteristics of the metric threads used will not be explained.

In the same embodiment, the angled hole 16 for plumb adjustment is a tapped hole and has a metric M4 thread.

The upper insert 10 is fixed to the base 20 via fixing screws 95 and a suitable adjustment screw 96, securing said base to said upper insert, itself secured to the upper crosspiece of the frame, thus forming the fixed assembly of the joint 100. The adjustment screw 96 also allows adjustment of the plumb of the opening.

The base 20, shown in perspective on the figure 1b and 2 , mainly comprises a ring 21 in which is made a bore 211 and a recess not visible in the figures. Indeed, the base 20 constitutes the female part of the joint 100 and is integral with the frame, the male part being formed by the assembly upstream of the base, with the axis 50 projecting, and integral with the opening, unlike the hinges of known doors in which the male axis is fixed to the frame while the female part is fixed to the sash thus causing a substantial bulk of the joint which is then visible and imposing on the frame.

The base 20, according to the illustrated embodiment, comprises ovalized holes 25 emerging, opposite the straight intermediate fixing holes 15 of the upper insert 10, in which are arranged the fixing screws 95 of metric M5. The base 20 further comprises a specific opening hole 26, the machining of which is suitable for receiving the adjustment screw 96 of metric thread M4 in an inclined position, said specific hole being located opposite the inclined hole 16 plumb adjustment made in the upper insert 10.

As illustrated on the figure 8 , the base 20 is slidably mounted in a groove 320 of the upper crosspiece 310 of the frame 300 of the frame, the fixing screws then make it possible to immobilize said base against said upper crosspiece.

Indeed, the ovalized holes 25 of the base 20 allow said base to slide in the groove 320 of the upper crosspiece 310 of the frame 300 when the fixing screws 95 engaged in said ovalized holes are unscrewed. This sliding of the base 20 then allows adjustment of the plumb of the opening using the adjustment screw 96. The tightening of the fixing screws 95 then makes it possible to freeze the position of the base 20 with respect to to the upper insert 10 and thereby even relative to the frame of the frame.

Each fixing screw 95 passes through an ovalized hole 25 of the base 20 until the head of said straight screw abuts in a counterbore 251 of said ovalized hole, the threaded rod of said straight screw extending outside the base 20 is screwed into the intermediate fixing hole 15 opposite said ovalized hole, in the upper insert 10, and in a fixing hole of the upper crosspiece of the frame.

In the same way, the adjustment screw 96 cooperates with the specific hole 26 of the base 20, the inclined hole for adjusting the plumb 16 of the upper insert, and a suitable hole in the upper crosspiece of the frame.

There is thus obtained a robust clamping of the fixed assembly of the joint 100, that is to say the upper insert 10 and the base 20, against the fixed frame of the frame, thus forming the female part of said joint, the male part, fixed as for it to an amount 210 of the opening 200 of the frame, is described below.

The male part of the hinge 100 mainly comprises the pin 50, the plug 30 concealing said pin at the top of the sash jamb, the brush 40, the lower insert 60, the locking insert 70, the retainer 80, and a suitable set of screws.

Axis 50, shown in its entirety at figure 1b , is a solid cylindrical rod of circular cross-section chamfered at both ends. The axis 50 is made of a material having sufficient mechanical strength and rigidity to withstand a heavy load on the frame and intensive use of said frame, such as for example a metal alloy based on Nickel and Chromium, preferably an X8CrNiS18-09 alloy according to European standard EN 10088.

In the illustrated embodiment, the axis 50 has a length of 80 mm.

The axis 50 engages in the lower insert 60 by an upper face of said lower insert as illustrated in the figure 1b , said axis being tightly mounted in the lower insert to be integral with said lower insert.

The lower insert 60, shown in figure 5 , is a parallelepipedal block comprising a longitudinal bore 61 opening into which is formed a recess 611 opening onto the upper face of said lower insert. Pin 50 is engaged in recess 611 as far as a shoulder 612, resulting from the variation in diameter of bore 61, against which said pin abuts. Thus, the axis 50 has an overrun over a useful length, corresponding substantially to the difference between the length of said axis and a depth of the recess 611, outside the lower insert 60. This overrun allows the axis 50 to s engage in cap 30 and base 20.

In the illustrated embodiment, the useful length of the overrun of the axis 50 with respect to the upper face of the lower insert 60 is 29 mm for example.

The lower insert 60 further comprises smooth holes 65 and a tapped hole 64 through which the said lower insert can be assembled with the locking insert 70.

The stopper 30, shown in picture 3 , is a structure having a shape and dimensions adapted to hide a major part of the base 20 and of the axis 50 while integrating as well as possible into the visual appearance of the door frame at the level of the frame of the opening 200 and the upper crosspiece of the frame. The plug 30 has visible faces, once the hinge 100 is mounted on the frame, shown hatched on the figure 1b and 3 and for which a paint type coating is necessary. A paint can for example be applied to these faces by a method of the lacquering type.

The cap 30, in addition to its aesthetic function, comprises a through hole 31 allowing the passage of the pin 50, said pin then joining the base 20, and a threaded hole 35 receiving the retaining screw 80 as will be described later.

The joint 100, according to the illustrated embodiment, comprises a robust sliding ring 51 having advantageous tribological performance, allowing improved fitting of the pin 50 in the ring 21 of the base 20.

Ring 51 allows axial and radial retention of pin 50 in the recess of bore 211, and is designed for maintenance-free application and dry operation without lubricant.

Preferably, the ring 51 is chosen from a range of rings marketed under the registered trademark Permaglide , and known for their low tendency to stick-slip phenomenon, low wear, good resistance to chemical attack, low coefficient of friction and inability to weld with metals.

The brush 40, represented on the figures 1a and 1b , has an adhesion edge 41 allowing said brush to stick to an upper side of the cap 30 as illustrated in the picture 1a . The brush 40 thus placed hides the base 20 between the plug 30 and the upper crosspiece of the frame, see figure 7 .

The brush 40 ensures the continuity of seals at the level of the upper crosspiece of the frame and at the upper end of the amount of the opening.

The locking insert 70, shown in figure 6 , is a profile having a geometric shape which generally takes the shape of the upper insert 10. The locking insert further comprises a longitudinal hole 71 that is smooth and emerges, and transverse holes 75 that are tapped.

In an exemplary embodiment, the retaining screw 80 comprises a smooth part 81 which extends from the screw head over a length less than the total length of the retaining screw, and a threaded part 85 which extends said part smooth to the free end of the retaining screw.

The retaining screw 80 engages in the longitudinal hole 71 of the locking insert 70 via its smooth part 81, and in the threaded hole 35 of the cap 30 by its threaded part 85.

The retaining screw 80 makes it possible to maintain the locking insert 70, the lower insert 60 and the pin 50 fixed in the upright of the sash and thereby constitutes a stop for the male part of the joint 100.

The fixing of the male part of the articulation 100 in the upright 210 of the opening 200 is carried out by screws which come to tighten in order the lower insert 60 and the locking insert 70 against a profile of the said upright , in the manner of clamping the base 20 and the upper insert 10 against a section of the crosspiece of the frame described above.

Indeed, screws 95 of metric M5 thread cooperate with the smooth holes 65 of the lower insert 60, the tapped holes 75 of the locking insert 70 and suitable holes, also tapped, in the upright 210 of the opening. .

A security screw 94 with metric M4 thread makes it possible to prevent any translation of the inserts, lower and locking, and of the axis in a longitudinal direction of the sash upright when the distal end of said screw security comes flush with an outer face 220 of the upright 210 of the opening, as illustrated in the figure 7 , said security screw then being in abutment on a lower edge of a hole 230 of the upright 210, said hole also allowing access to said security screw.
